Are Both Covid Vaccine Doses The Same

What About The Single Dose Vaccine

CDC recommends both COVID vaccine doses come from the same manufacturer

The one-dose Johnson & Johnson vaccine was on Saturday, Feb. 27.

The authorization came just a few weeks after the company announced its Emergency Use Authorization application to the FDA.

J& J says its vaccine, in addition to being just one dose, can be stored for “at least three months” in most standard refrigerators.

L.A. County Public Health director Barbara Ferrer previously said she is “hopefulthe Johnson & Johnson vaccine would be a good option for people experiencing homelessness, or who would otherwise face challenges returning for a second dose.

On the day the authorization was announced, Gov. Newsom tweeted that 380,000 doses should be heading to California ASAP. Los Angeles County health officials have said they believe about a quarter of those doses would be earmarked for L.A. County, the state’s most populous.

The New York Times has a vaccine guide from a professor of public health that explores the different options, and offers this advice:

  • “When there are multiple shots of varying effectiveness, take whatever is available to you first.”

What Are Your Questions About The Coronavirus Vaccine

ideastream’s health team is answering as many questions as possible, with help from local experts in a range of fields. You can send us your questions with our online form, through our social media group, or call us at . We’ll keep the answers coming on our website and on the air.

Aubrey from Cleveland asks: Is the second dose of the Pfizer or Moderna vaccine different than the first one?

The second dose is the same as the first dose, but Pfizer and Moderna are not interchangeable. The person administering the vaccine needs to know the brand of the first dose.

So, providers will make sure they are giving you the same brand for your first and second dose, says MetroHealths Dr. David Margolius.

Theyll also make sure you are getting the second dose at the right time.

For Pfizer, the minimum time between the doses is 21 days, while for Moderna, the minimum amount of time between doses is 28 days.

According to the U.S. Centers for Disease Control and Prevention people should wait no more than 6 weeks between doses.

What Are The Side Effects

After receiving a COVID-19 vaccine, you may have some side effects, which are normal signs that your body is building protection. Side effects are typically mild to moderate, occur within the first 3 days beginning the day of the vaccination, and resolve within 1-2 days of onset. Some people have no side effects.

Common side effects on the arm where you received the shot include pain, redness, and swelling. Throughout the rest of your body, you may feel tiredness, headache, muscle pain, chills, fever, and nausea.

Getting A Booster Shot

At this time, we can only provide Pfizer-BioNTech COVID-19 booster shots, based on CDC guidance. The FDA and CDC continue to review data to determine if theyll recommend booster shots for the Moderna and Janssen COVID-19 vaccines. We must wait for guidance before we can provide booster shots for these other vaccines.

Most Children And All Teens Can Get Covid


CDC recommends everyone ages 5 and older get a COVID-19 vaccine to help protect against COVID-19.

Vaccines Authorized For

Children 4 years and under:

  • None

Children 511 years old:

  • Pfizer-BioNTech

Teens 1217 years old:

  • Pfizer-BioNTech

Everyone 18 years and older:

  • Pfizer-BioNTech

J& J / Janssen

Widespread vaccination for COVID-19 is a critical tool to best protect everyone, especially those at highest risk, from severe illness and death. People who are fully vaccinated can safely resume many activities that they did prior to the pandemic. Children ages 5 years and older are able to get an age-appropriate dose of Pfizer-BioNTech COVID-19 Vaccine. Learn more about what you and your child or teen can do when fully vaccinated.

I Got My First Dose At A Site Run By Riverside County

You can see which sites offer second dose appointments and book one for yourself on the public health website.

You should get an email about your second dose.

The email should contain “an invitation” to book a second dose appointment at a specific clinic, according to Dr. Geoffrey Leung of the Riverside County Health System.

But that email might not come immediately – or even by the date listed on your white vaccination record card.

“A little bit of the second dose notifications may be behind the schedule that people were anticipating,” public information officer John Welsh said on Feb. 16. “But you will be getting that notification, just please be patient with us.”

If you got your first dose before Jan. 22, Leung said you should’ve gotten your email already. If not, you can email public health representatives at .

Experts urge you not to try go get your second shot early by altering the date on your vaccine card.

Then-Riverside County Health Officer Cameron Kaiser tweeted “Getting vaccinated too soon could impact the reliability of the vaccine.”

So don’t do that.

Why Canada Has Been Slow To Get Covid

While Canada’s approach could change based on any gleanings from these studies, he does not recommend mixing vaccines until there is evidence to support it.

“Theoretically, yes, they could be synergistic, but theoretically they could blunt each other out, you might make the wrong response to one and then have the other on board,” he said. “And so as much as we think one plus one equals two, it may not. It may be one plus one equals zero in this sense.”

Last Week Health Minister Mansukh Mandaviya Had Told The Lok Sabha That The National Technical Group On Immunisation And The National Expert Group On Vaccine Administration For Covid

New Delhi: The National Technical Group on Immunisation will be holding a meeting on Monday to decide on the possibility of administering additional doses of vaccine to immunocompromised individuals. The development comes against the backdrop of India’s rising Omicron case tally and growing calls for booster jabs to be made available. According to sources, the meeting will include scientists from across the country.

Reportedly, the NTAGI is also slated to take up the issue of child immunisation today. While the country has so far administered more than 1.27 billion jabs, children remain ineligible under the nationwide vaccination drive. Two vaccines have received emergency usage authorisation for use on children. However, they are yet to become available to the public.

Health officials have differentiated between booster and additional doses, stating that the eligibility criterion is somewhat different. While both will be administered to people who have already been ‘fully vaccinated’, an additional dose is given to people facing problems with their immune functions in case they do not develop sufficient immunity to COVID-19. Meanwhile, a booster jab is given after a fixed period of time to individuals who have received two doses.

How Does The Two

Patients must get both COVID-19 vaccine doses from same facility

At your first appointment, youll receive a vaccination card noting the manufacturer of the vaccine you receive, the dose and date. Keep the card youll need to present it to get the second shot and might need it in the future to prove youve been vaccinated. Tip: Take a photo of the card as a backup in case you lose it.

Your second dose should be the same manufacturer as your first shot, and in most cases you will receive it from the same vaccinator and likely in the same location. The process for scheduling your second-dose appointment differs depending on which vaccinator provides your shots.

Who Should Get An Additional Dose Of Vaccine

Currently, individuals with moderately to severely compromised immune systems are recommended for an additional dose of COVID-19 vaccine if they previously received a two-dose primary series of either the Pfizer BioNTech or Moderna COVID-19 vaccines. This includes people currently receiving treatment for cancer, people taking medications that weaken the immune systems, organ or stem cell transplant recipients, individuals with advanced or untreated HIV infection, and other conditions. A full list of conditions can be found on CDCs website. If you are unsure if you are recommended for an additional dose, talk with your health care provider. The third dose of Pfizer BioNTech or Moderna COVID-19 vaccine can be given anytime 28 days after receiving the second dose.

An additional dose is being recommended after emerging data suggests some people with moderately to severely compromised immunes systems do not always build the same level of immunity as individuals who do not have a compromised immune system. An additional dose will help ensure people with compromised immune systems get as much protection as possible from COVID-19 vaccination.

When Do I Need To Get My Second Dose

If your first dose was the Pfizer vaccine: three weeks apart .

If your first dose was the Moderna vaccine: four weeks apart .

But there is a little wiggle room.

You have up to six weeks , according to the Centers for Disease Control and Prevention.

On Jan. 21, the CDC’s guidance was updated:

  • “The second dose should be administered as close to the recommended interval as possible. However, if it is not feasible … vaccines may be scheduled for administration up to 6 weeks after the first dose.”

Who Should Get A Pfizer

The CDC recommends that these groups should get a booster shot if they completed their Pfizer-BioNTech primary vaccination series at least 6 months ago:

  • People who are at least 65 years or old
  • People who live in long-term care facilities
  • People who are 50 to 64 years old and have an underlying medical condition

Will More People Eventually Need Additional Doses Of The Covid

Malta Has Ordered Enough COVID

Its almost certain that most people will eventually need to get booster shots or additional doses of the vaccines. However, we are still studying how long the vaccines will protect people. The good news is that people who are healthy should still have ample protection from their COVID-19 vaccines. While some healthy, vaccinated people do get COVID-19 infections, they are much less common than in unvaccinated people and they are much less severe. This is why its important for people who havent received their vaccine yet to get it right away.

    Preparing Children And Teens For Vaccination

    The experience of getting a COVID-19 vaccine will be very similar to the experience of getting routine vaccines. Use our tips to support your child before, during, and after routine vaccinations when they get a COVID-19 vaccine.

    • Talk to your child before vaccination about what to expect.
    • It is not recommended you give pain relievers before vaccination to try to prevent side effects.
    • Tell the doctor or nurse about any allergies your child may have.
    • To prevent fainting and injuries related to fainting, your child should be seated or lying down during vaccination and for 15 minutes after the vaccine is given.
    • After your childs COVID-19 vaccination, you will be asked to stay for 1530 minutes so your child can be observed in case they have a severe allergic reaction and need immediate treatment.

    Do Both Coronavirus Vaccine Doses Need To Be The Same To Work

    Although no studies have yet been published to confirm it, its extremely likely mixing vaccines will still produce a strong immune response, according to Matthews.

    This isnt to say the vaccines are identical the Oxford adenoviral vaccine works differently from the Pfizer and Moderna mRNA jabs. While the Oxford vaccine prompts some of your cells to reproduce genetic instructions , the mRNA vaccines instead deliver these instructions straight to your cells.

    The bottom line of it is that all the approved vaccines are designed to make cells in your body to produce these spikes, which mimics how the coronavirus works. They all trick your immune system into thinking its infected with COVID-19, preparing it for a real thing. While their methods differ, the outcome is the same, says Matthews.

    So, from a biologists perspective, theres no reason why you couldnt mix the two.

    Sure, its not forbidden by the laws of physics that there might be some biology at play that we dont know about. But, at the moment, youd have to be on some really powerful hallucinogenic drugs to come up with why it wouldnt work.

    In fact, some scientists predict two doses from different manufacturers will produce a better immune response than sticking to one type. After all, the idea of mixing vaccines has been previously shown to boost immunity against diseases such as SARS.

    In short: not only is mixing vaccines probably safe, but it could soon be the norm.

    Canadians Should Get Same Covid

    The National Advisory Committee on Immunization has recommended that Canadians receive the same COVID-19 vaccine for both doses.

    The agency on May 21 to include the recommendation for second shots, as well as what should be done if a vaccine candidate is not available.

    NACI said that if the vaccine that was used for someones first dose is not accessible, attempts should be made to give them a second dose of a similar type of vaccine.

    So, if a persons first dose was an mRNA vaccine, their second dose should also be an mRNA vaccine. Pfizer and Moderna are the only two mRNA vaccines approved for use in Canada.

    There is no reason to believe, NACI said, that there would be any additional safety issues or deficiency in protection if someone got a dose of Pfizer and then a shot of Moderna, or vice versa.

    Similarly, if someone receives one dose of AstraZeneca and cant get a second, they can have a shot of Johnson & Johnson. The two are the sole viral vector vaccines approved in Canada.

    The individual must understand the risk for rare but serious blood clots, known as vaccine-induced thrombotic thrombocytopenia , that comes with the viral vector vaccines.

    Cases of VITT are reportedly lower with second doses than with first, NACI said.

    Despite the updated guidance, NACI clarified that there is currently no data on the interchangeability of vaccines.

    Am I Eligible For A Third Dose Of The Covid

    In the United States, only people with weakened immune systems are currently eligible for a third dose of the COVID-19 vaccine. The Centers for Disease Control and Preventions Advisory Committee on Immunization Practices says these doses for now should go to only those who are immunocompromised and who received the mRNA vaccines made by Pfizer or Moderna.

    While that is expected to change later this year, this group currently includes patients whove had or are receiving:

    • Organ transplants
    • Stem cell transplants within the past two years
    • Active cancer treatment for tumors or blood cancer and are undergoing chemotherapy that affects the immune system
    • Severe primary immunodeficiency
    • Advanced or untreated HIV
    • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response.

    There is not enough data yet to know whether immunocompromised people who got the one-dose Johnson & Johnson vaccine need another dose, but we expect to know more soon.

    You are not eligible for a third dose of the vaccine at this time if you are healthy, do not have one of these specific conditions, or do not take certain immunosuppressive medications. However, if you received a Moderna or Pfizer vaccine, you will be eligible for a booster shot eight months after your second dose.
