How Long To Wait Between Covid Vaccines

Heres What Weve Learned About Spacing Out Covid

How long do you have to wait between other vaccines and coronavirus vaccine?

Studies and real-world evidence have shown that extending the time between the first and second doses of the Pfizer and Moderna shots improvesimmunity.

A paper published in the journal Nature found that extending the duration between the Pfizer doses to 12 weeks led to a more robust antibody response. Another recent study from the Mayo Clinic found that people who got vaccinated with Pfizer were more likely to get a breakthrough infection compared to those who got the Moderna shots.

Even four weeks made a difference as opposed to having three weeks between doses, Gandhi said.

The real-world evidence from Canada and the U.K., where vaccine scarcity forced people to separate their doses up to four months, compared to the United States and Israel where there were plenty of vaccines also suggests theres some added protection in delaying the second dose.

The vaccine efficacy against symptomatic illness is lower in Israel and the U.S. and both countries opted for a three-week strategy for Pfizer, whereas Canada and the U.K. both have not reported reduction in vaccine effectiveness against symptomatic COVID, Gandhi said.

Do I Qualify For An Additional Dose Of The Covid

The CDC recommends an additional dose for patients with the following conditions:

  • Active or recent treatment for cancer
  • Previous stem cell transplant or CAR T-cell therapy
  • Previous solid organ transplant
  • Moderate or severe primary immunodeficiency
  • Advanced or untreated HIV infection
  • Active treatment with immune-suppressing medications, including high-dose corticosteroids, chemotherapy, tumor necrosis factor inhibitors, and other biologic agents that suppress or modulate the immune system

This recommendation only applies to individuals who received an mRNA vaccine, in other words, the Pfizer or Moderna vaccine. At this time, the CDC is not recommending an additional dose for patients who received the Johnson & Johnson/Janssen vaccine, even if they are immunocompromised.

What You Need To Know

  • If you receive a Pfizer-BioNTech or Moderna COVID-19 vaccine, you will need 2 shots to get the most protection.
  • COVID-19 vaccines are not interchangeable. If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot.
  • You should get your second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.
  • If you have a weakened immune system due to other diseases or medications, you can receive a COVID-19 vaccine if you have not had a severe or immediate allergic reaction to any of the ingredients in the vaccine.
  • People with moderately to severely compromised immune systems should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.

What Is The Current Government Recommendation

Although doses of the Pfizer vaccine can be given a minimum of 21 days apart and the Oxford/AstraZeneca and Moderna vaccines can be given a minimum of 28 days apart, the JCVI currently recommends an interval of eight to 12 weeks of all approved vaccines.

According to the Government, the consistent interval is used both to avoid confusion and simplify booking as well as to ensure a good balance between achieving rapid and long-lasting protection.

There are exceptions however, including for those about to commence immunosuppressive treatment, such as chemotherapy. In those instances, people can receive a second dose after a shorter interval to ensure the vaccine is given while their immune system is better able to respond.

Second Dose Of COVID

If you cant leave a space of seven days between having the two vaccines, where does that leave you? For now, PHE suggests that where individuals in an eligible cohort have received another vaccine, Covid-19 vaccination should still be considered.

The same applies for other vaccines where Covid-19 vaccination has been received first.

In many cases, vaccination should proceed to avoid any further delay in protection and to avoid the risk of the patient not returning for a later appointment, says PHE.

In such circumstances, patients should be informed about the likely timing of potential adverse events relating to each vaccine.

People do not have to have had a flu jab in order to have the Covid-19 vaccine.

Who Is Recommending An Additional Dose Of The Covid

The U.S. Food and Drug Administration amended the emergency use authorizations for both the Pfizer and Moderna COVID-19 Vaccines to allow for the use of an additional dose in certain immunocompromised individuals. The Centers for Disease Control now recommends an additional dose for these patients. This is as a result of medical studies suggesting a reduced antibody response after the usual two-dose vaccine primary series.

Booking Your 2nd Dose

You’ll usually need to book a 2nd dose for 8 to 12 weeks after your 1st dose.

  • If you book online, you’ll be asked to book appointments for both doses. You can manage your COVID-19 vaccination appointments to view your appointments and rebook if you need to.
  • If you’re 18 or over and have your 1st dose at a walk-in vaccination site, you can book your 2nd COVID-19 vaccination appointment online. You’ll need to wait 24 hours after your 1st dose before you can book.
  • If you have your 1st dose through your GP surgery, you’ll be contacted when it’s time to book your 2nd dose.

Is The Second Dose Necessary

Because both vaccines appear to have high effectiveness 14 days or more after the first dose, you may be wondering whether the second dose of the vaccine is actually necessary.

Its true that there have been discussions amongst public health officials and scientists about the possibility of delaying or eliminating the second dose of these vaccines.

The thought process behind this is that either delaying or eliminating the second dose would enable a greater number of people to get some level of protection. It would also aid in stretching vaccine supplies to more people.

However, there are some concerns about doing this. Its possible that overall immunity or vaccine effectiveness could be impacted. Additionally, lower levels of immunity could drive the emergence of more virus variants that can escape our current vaccines.

Additional research into delaying or eliminating second doses is needed. Currently, the FDA

Side effects that are felt throughout your body, such as fever, fatigue, and headache, are more common after getting the second dose of the vaccine. This is true for both the Pfizer-BioNTech and Moderna vaccines.

Remember that the first dose of the vaccine generates a weaker response than the second dose. Because of this, youre more likely to feel side effects after the second dose.

We Often Space Out Doses With Other Shots

How Long To Wait Between Vaccine, Mammogram? Dr. Mallika Marshall Answers Your COVID-19 Questions

Scientists who study vaccines werent surprised to learn that extending the window between doses produced a better immune response.

This has been known long before COVID-19, said Isaac Bogoch, an infectious diseases physician and scientist with University of Toronto.

Many of the vaccines used to protect us against other infectious diseases have multiple doses that are separated by months. Why? Because data from vaccinology, in general, suggests that extending time between doses strengthens immunity.

A 2018 study on messenger RNA vaccines from before the pandemic found that when mRNA doses are spaced out longer, the body creates stronger T cell and B cell responses .

This idea of extending the time between doses is not an accident, Bogoch said. People will form a more robust immune response with the doses separated apart, he explained.

The two Hepatitis A shots are separated by six months. With the Hepatitis B shot, the second dose is given four weeks after the first, and the final dose is given eight weeks after the second. Children getting the measles-mumps-rubella vaccine routinely get the second dose three months after the first but its OK if they miss the exact time and come in a couple months later.

Does It Prevent Infection And Transmission

There is currently no substantive data available related to the impact of COVID-19 vaccine BIBP on transmission of SARS-CoV-2, the virus that causes COVID-19 disease.

In the meantime, WHO reminds of the need to maintain and strengthen public health measures that work: masking, physical distancing, handwashing, respiratory and cough hygiene, avoiding crowds and ensuring adequate ventilation.

Time Between Doses Of Covid

The time between doses of the COVID-19 vaccine is being increased, Director-General of Health Dr Ashley Bloomfield says.

From today, the standard time will become 6 weeks between the first and second doses of the vaccine, he says.

Moving to a longer gap allows us to give a first dose to a larger number of people faster, which means providing more people with partial protection sooner. This is an important part of our being prepared for a possible outbreak of the more infectious Delta variant of the virus.

Early findings from a small number of well-designed studies show that an extended duration between doses of the Pfizer vaccine gives at least an equally robust immune response, with no additional safety concerns.

This new guidance is in line with other international programmes using the Pfizer vaccine. For example, the interval between doses in Denmark and Norway ranges between 6 and 12 weeks, while the United States uses 3 weeks but allows up to 6 weeks.

The larger interval is also consistent with the advice from the COVID Technical Advisory Group for an extended interval between doses to reduce the likelihood of a rare side effect of myocarditis or pericarditis.

I do want to reassure people that if you have already been fully vaccinated with two doses less than 6 weeks apart, as we have been doing, you will have very strong protection against the virus and do not need to doubt that.

These Are The Main Side Effects Of The Coronavirus Vaccine

Is there an order that works best to have both the vaccines in?

Theres no preference on either vaccine first, says a DHSC spokesperson, but the current Covid vaccine rollout is obviously limited and by the time most people are offered the Covid-19 vaccine, they will likely have been offered the flu vaccine already.

Experts are still learning about Covid-19. The information in this story is what was known or available at the time of publication, but guidance could change as scientists discover more about the virus.To keep up to date with health advice and cases in your area, visit gov.uk/coronavirus and nhs.uk.

Children And Young People Aged 12 To 17

Preparing for Your COVID

People aged 16 and 17, and children aged 12 to 15 who are eligible, will be contacted by a local NHS service such as a GP surgery to book their vaccination appointments.

Some walk-in COVID-19 vaccination sites are offering the vaccine to people aged 16 and 17. You can check if a site is available near you.

Recommendations On Authorized Available Covid

These recommendations apply only to COVID-19 vaccines currently authorized for use in Canada . In considering these recommendations and for the purposes of publicly funded program implementation, provinces and territories may consider local programmatic factors and local epidemiology .

  • NACI preferentially recommends that a complete series with an mRNA COVID-19 vaccine should be offered to individuals in the authorized age group without contraindications to the vaccine.

  • NACI recommends that a viral vector COVID-19 vaccine may be offered to individuals in the authorized age group without contraindications to the vaccine to initiate a series when other authorized COVID-19 vaccines are contraindicated or inaccessible. Informed consent should include discussion about the risk and symptoms of VITT, as well as the need to seek immediate medical care should symptoms develop.
  • Refer to Table 5 for a summary of evidence and factors for jurisdictions to consider when implementing COVID-19 immunization programs.

    Summary of evidence and rationale:

    mRNA COVID-19 vaccines

    Informed consent for mRNA COVID-19 vaccines should include information about very rare reports of myocarditis or pericarditis in the week following an mRNA vaccine

    AstraZeneca COVID-19 vaccine

  • In clinical trials, the majority of local and systemic adverse events with the AstraZeneca COVID-19 vaccine were mild and transient and did not differ by dose administered or age.
  • Immunosuppressed persons

    Who Should Be Vaccinated First

    While COVID-19 vaccine supplies are limited, health workers at high risk of exposure and older people should be prioritized for vaccination.

    The vaccine is not recommended for persons younger than 18 years of age, pending the results of further studies in that age group.

    Countries can refer to the WHO Prioritization Roadmap and the WHO Values Framework as guidance for their prioritization of target groups.

    Allow For Gap Between Flu And Covid

    Image 1 of 10

    A woman receives a dose of the Pfizer-BioNTech Covid-19 vaccine at Zabeel Health Centre in Dubai.

    There should be a gap of at least 14 days between the vaccines to allow the body to develop immunity, experts say.

    People should not think twice as this flu vaccine is different from the Covid vaccine, so it is important they take it, said Dr Hind Al Awadhi, head of health promotion and education at Dubai Health Authority.

    There is no reason not to , we only ask people to leave a gap of two weeks between doses to give their body enough time to develop some immunity,” she said.

    Getting Your Second Dose Increases Protection

    How long should you wait to get the COVID-19 vaccine after getting a pneumonia shot?

    For the best protection, it’s important to get 2 doses of the vaccine. The standard gap between doses is now 6 weeks or more.

    We are extending the standard gap because it allows us to give 1 dose to a larger number of people faster.

    Clinical trials showed the Pfizer vaccine had a higher efficacy against symptomatic COVID-19 infection after receiving the second dose. This is supported by recent real-world data.The first dose primes your immune system but protection doesnt last as long because the level of antibodies falls. A second dose gives your immune response a boost with lots more antibodies to help your immune response to mature and provide longer protection.

    Having The Covid Vaccine During Pregnancy

    The Royal College of Obstetricians and Gynaecologists told us: It is important to have the flu vaccine as well as the COVID-19 vaccine in pregnancy. The NHS is advising waiting one week between receiving the different vaccines against flu and COVID-19. We would encourage all pregnant women to have any routine vaccines and the COVID-19 vaccine to protect themselves and their babies against illness.

    It previously told Full Fact that as far as timings between Covid vaccine doses, in the UK, second doses are given eight to 12 weeks after the first dose, with high risk people being able to bring their second dose forward to eight weeks. While pregnant women are not currently included in this group, the RCOG recommended contacting your GP or the National Booking System to see if the second dose can be brought forward to eight weeks.

    The Covid-19 vaccine is now recommended in pregnancy in the UK. Severalstudieshave shown that severe Covid illness is more likely for women who are pregnant than those who arent, especially for those in the third trimester.

    There is more real-world safety data from the US in pregnant women for the Pfizer and Moderna vaccines, so the Joint Committee on Vaccination and Immunisation advises that those vaccines be offered in pregnancy.

      New And Emerging Research Priorities

      Efficacy, effectiveness, immunogenicity and safety

    • What is the population effectiveness and medium and long-term durability of protection of a single dose or a complete series of each COVID-19 vaccine approved in Canada?
    • What is the efficacy, effectiveness, immunogenicity, and safety of COVID-19 vaccines across diverse population groups ? Is a third booster dose of vaccine or a higher dose of vaccine needed to elicit an appropriate immune response in these individuals?
    • What is the efficacy, effectiveness, immunogenicity and safety of COVID-19 vaccines in individuals who have had a previous laboratory evidence of SARS-CoV-2 infection?
    • Is there a discernable difference between seronegative and seropositive people in any of the above parameters?
    • Does previous exposure to SARS-COV-2 impact efficacy, effectiveness, immunogenicity or safety of COVID-19 vaccines?
    • Can a single-dose vaccine series be as effective and safe in individuals with previously proven COVID-19 disease?
    • Are there any emerging safety signals with COVID-19 immunization that are not predicted by the current understanding of the safety profile of similar vaccines?
    • Does vaccination following prior SARS-CoV-2 infection or vaccination of SARS-CoV-2 naïve individuals elicit enhanced or altered disease upon subsequent infection by SARS-CoV-2 or other endemic coronaviruses?
    • What is the efficacy, effectiveness, immunogenicity and safety of COVID-19 vaccines against SARS-CoV-2 variants of concern?
    • Vaccine administration

      These People Are Being Urged To Get The Flu Vaccine Before Christmas

      As it stands, because the vaccine is so new, we dont really know how the Covid-19 vaccine and flu vaccine would interact with one another, as no data on co-administration of the Covid-19 vaccine with other vaccines exists.

      But in the absence of such data, its been suggested that interference between the flu and Covid-19 vaccines, which have different antigenic content is likely to be limited.

      Based on experience with other vaccines, any potential interference is most likely to result in a slightly attenuated immune response to one of the vaccines, says PHEs spokesperson, before adding there is no evidence of any safety concerns.

      How To Get Your Covid

      If Your Vaccine Side Effects Last This Long, Get a COVID ...

      The COVID-19 vaccines currently available are given in 2 doses. You usually have the 2nd dose 8 to 12 weeks after the 1st dose.

      If you’re aged 18 or over you can:

      If you cannot book appointments online, you can call 119 free of charge. You can speak to a translator if you need to.

      If you have difficulties communicating or hearing, or are a British Sign Language user, you can use textphone 18001 119 or the NHS 119 BSL interpreter service.
