Can I Mix Covid Vaccines
It is not recommended. For now, Pfizer vaccine recipients are advised to get a Pfizer booster shot, and Moderna and Johnson & Johnson recipients should wait until booster doses from those manufacturers are approved. Some people who received the Johnson & Johnson vaccine have sought a Pfizer booster shot. Some local health officials have said they will accommodate such requests as long as people consult with their doctors first.Tara Parker-Pope
How Many Children Were Studied In The Clinical Trials And For How Long
Pfizers trial included 2,268 children ages 5 to 11, two-thirds of whom received two doses of the vaccine three weeks apart the rest were injected with two doses of saltwater placebo. Given how rarely children become severely ill, the trial was not big enough to draw meaningful conclusions about the vaccines ability to prevent Covid or hospitalization. Instead, the researchers relied on measurements of the children’s immune response, on the assumption that the protective levels of antibodies seen in older people would be as protective in younger children.
The Pfizer study for older children enrolled 2,260 participants ages 12 to 15. Of those children, 1,131 received the vaccine and 1,129 received saline placebo shots. The vaccine worked even better in children than it did in adults. No children in the vaccine group got sick with Covid-19, while 18 children in the placebo group became ill. The company is still gathering information, including testing the trial participants every two weeks for the coronavirus.
Moderna recently released the results of its trial testing the vaccine in 3,732 people ages 12 to 17, two-thirds of whom received two vaccine doses. There were no cases of symptomatic Covid-19 in fully vaccinated adolescents, the company reported.

Will The Vaccine Affect My Fertility Treatment Schedule
Fertility patients who are scheduled for procedures like egg retrieval, embryo transfer or intrauterine insemination are advised to avoid getting a Covid vaccine within three days before and three days after the procedure, according to the American Society for Reproductive Medicine. Thats because patients undergoing surgical procedures could develop vaccine-related side effects like fever or chills that might make it difficult for doctors to know if a post-surgical infection is brewing. In addition, many medical providers may not allow a patient who is experiencing Covid-like symptoms into their facility, even if its likely that the symptoms are from a vaccine and their Covid-19 test is negative.Christina Caron
Newsgaps Contradictions And Delays: Powerful Tool In Pandemic Is Going Wasted
But the body’s immune response doesn’t expire after a set interval.
“Your immune system is really smart,” said Dr. Buddy Creech, director of the Vanderbilt Vaccine Research Program at Vanderbilt University Medical Center in Nashville, Tennessee. “It doesn’t forget what it saw the first time,” he said, referring to the first vaccine dose.
Creech, who has overseen clinical trials for Moderna, said the vaccines should work as expected, even if the second dose is delayed a month or more than what is recommended.
“Do not panic. Even if it’s four weeks, six weeks, eight weeks before you can get that second dose, it’s fine from an immune system standpoint,” he said.
The second dose of both the Pfizer and Moderna vaccines function as a reminder to the immune system.

“Like any defense mechanism, if the immune system sees something once, it may be prepared the second time,” said Dr. Bruce Y. Lee, a professor of health policy and management at the City University of New York. “If you’re exposed to something a second time, it tells you hey, you’ve got to treat this seriously.”
That could happen even if the second dose was given as much as a year later, said Dr. Diane Griffin, an infectious disease expert at the Johns Hopkins University School of Medicine, though there is no data showing that giving the second dose that much later would lead to the 95 percent effectiveness seen in the clinical trials.

Is It Ok If My Two Covid
Once youre given one type of vaccine, the second vaccine dose should be the same type, from the same manufacturer as the first vaccine dose. The Pfizer/BioNTech and Moderna mRNA COVID-19 vaccines are not interchangeable with each other or with other COVID-19 vaccine products. Each vaccine is manufactured differently even those that use similar underlying technology, such as Pfizer and Moderna.
Shortly after your first vaccination, your record will show which type you received, so you can schedule your second shot with the same brand and at the proper time interval between doses.
These recommendations may change as further information becomes available or as other vaccine types are authorized for use. In rare cases, such as in the event of an allergic reaction, an exception may be made to allow for the second dose from a different manufacturer.
Do Vaccines Cause Blood Clots
Two vaccines, Johnson & Johnson and AstraZeneca, have been linked to extremely rare clotting disorders. In the United States, federal health regulators have told Johnson & Johnson to add a warning to its label to note the potential risk of rare blood clots. European regulators who concluded that a vaccine made by AstraZeneca may also be the cause of a similar, extremely rare clotting disorder. In both cases, the risk is iinfinitesimal, and health officials have said the shot’s benefits outwieigh the risk. The F.D.A. has not found a higher risk of clotting disorders in people who have received the Moderna or Pfizer-BioNTech vaccines.Emily Anthes, Carl Zimmer and Noah Weiland
Reporting A Possible Serious Reaction
Contact your health care provider if you experience:
- a side effect following vaccination with a COVID-19 vaccine
- any persistent, new or worsening symptoms
Health care providers must report possible reactions following vaccination to their local public health authority. The public health authority then reports them to the Public Health Agency of Canada.
Reported allergic reactions and side effects to COVID-19 vaccines are published weekly in our Reported side effects following COVID-19 vaccination report.
How Long Does The Immunity Last
Moderna recently announced no change in efficacy six months after participants received their COVID-19 vaccines, with a 93% protection against severe disease after six months, compared to 94% reported in the clinical trial.
Pfizer has reported similar data, with protection sitting at 84% after six months.
No longer term effectiveness studies have been possible, as the wide-scale vaccine rollout only commenced at the end of 2020.

I Have An Autoimmune Disease Will The Vaccine Work For Me
An estimated 8% of Americans have an autoimmune disease such as rheumatoid arthritis or lupus, which occur when the immune system mistakenly attacks normal body tissues. Although people with autoimmune conditions were allowed to enroll in the Covid vaccine trials, patients were excluded if they were taking the type of immune-suppressing drugs used to treat autoimmune disorders. As a result, doctors believe the vaccine is safe for people with autoimmune conditions, but they dont have specific data showing how well the vaccine works in these patients. The National Institutes of Health has announced a new study to determine whether people with autoimmune conditions should receive a third dose of Covid vaccine, similar to the immunization schedule approved for patients with weakened immune systems. The study will also investigate whether pausing immunosuppressive therapy for autoimmune disease improves the antibody response to an extra dose of a COVID-19 vaccine. In the meantime, patients with autoimmune conditions should consult with their physicians about getting the Covid vaccine.Dani Blum
Will The Vaccines Work Against The New Variants That Have Emerged Around The World
While the rise of more infectious variants, including the highly-infectious Delta variant, has caused cases of Covid-19 to surge around the world, the risk is primarily to the unvaccinated, for whom there is great concern. But for the vaccinated, the outlook is much more hopeful. While its true that the vaccines have different success rates against different variants, the perception that they dont work against variants at all is incorrect. In fact, the available vaccines have worked remarkably well at preventing serious illness and hospitalization, even as new variants circulate around the globe.
The variants are all the more reason to get vaccinated, said Dr. Anthony S. Fauci, the nations top infectious disease specialist. The bottom line is the vaccines we are using very well protect against the most dominant variant we have right now, and to varying degrees protect against serious disease among several of the other variants.Tara Parker-Pope

Does It Work Against New Variants
Based on the evidence so far, the new variants of SARS-CoV-2, including the B.1.1.7 and the 501Y.V2, do not alter the effectiveness of the Moderna mRNA vaccine. The monitoring, collection and analysis of data on new variants and their impact on the effectiveness of COVID-19 diagnostics, treatments and vaccines continues.
Vaccination Card And Your Second Shot
At your first vaccination appointment, you should have received a vaccination card that tells you what COVID-19 vaccine you received, the date you received it, and where you received it. Bring this vaccination card to your second vaccination appointment.
- If you did not receive a COVID-19 vaccination card at your first appointment, contact the vaccination provider site where you got your first shot or your state health department to find out how you can get a card.
- If you have lost your vaccination card or dont have a copy, contact your vaccination provider directly to access your vaccination record.
- If you cannot contact your vaccination provider directly, contact your state health departments immunization information system . You can find state IIS information on the CDC website. Vaccination providers are required to report COVID-19 vaccinations to their IIS and related systems.
- If you enrolled in v-safe or VaxText after your first vaccine dose, you can access your vaccination information using those tools.
- If you have made every effort to locate your vaccination information, are unable to get a copy or replacement of your vaccination card, and still need a second shot, talk to a vaccination provider.

Is There A Risk Of Developing Covid
No. The Pfizer, Moderna and Johnson & Johnson vaccines approved in the United States do not contain any live virus, weakened virus, dead virus or any infectious element, so there is no way for the vaccine to give you Covid-19. The best way to understand the mRNA vaccines is that they carry a set of instructions to teach your bodys immune system how to attack the coronavirus. The Johnson & Johnson vaccine uses a different technology to send similar instructions.Tara Parker-Pope
Why Not Take My Chances With Covid
Covid-19 is by far the more dangerous option. Covid vaccines carry little known risk. But the perils of Covid-19 have been well documented. About 20 percent of people who come down with Covid-19 symptoms develop serious, potentially life-threatening illness. Although people who are older, obese or have other health problems are at highest risk for complications from Covid-19, younger people can become severely ill, too. In a study of more than 3,000 people ages 18 to 34 who were hospitalized for Covid, 20 percent required intensive care and 3 percent died.
The long-term health complications associated with Covid-19 are a serious concern. As many as one in three people who recover from Covid have chronic complaints for months afterward, including exhaustion, a racing heart, blood clots and loss of sense of smell or taste.Apoorva Mandavilli

Eu Agency Approves Moderna’s Covid
An interval of 28 days between doses is the most highly recommended time span, but the WHO has said that boosters can be delayed by up to 42 days if necessary.
The WHO’s Strategic Advisory Group of Experts on Immunization , issued the series of recommendations on Moderna, several weeks after issuing their guidance on the rival BioNTech-Pfizer shot.
“The main recommendation for the use of this vaccine is that based on the current elements we recommend it should be given in doses of 100 micrograms or 0.5 ml with an interval of 28 days,” Alejandro Cravioto, panel chair, told a news briefing in Geneva.
“This interval might be moved to 42 days but the evidence we have does not go behond that time,” he said, speaking from Mexico.
What Spikevax Contains
- This vaccine contains polyethylene glycol/macrogol as part of PEG2000-DMG.
This is a multidose vial which contains 10 doses of 0.5 mL.
One dose contains 100 micrograms of messenger RNA .
Single-stranded, 5-capped messenger RNA produced using a cell-free in vitro transcription from the corresponding DNA templates, encoding the viral spike protein of SARS-CoV-2.
The other ingredients are:
- Water for injections.

How The Vaccine Works
Spikevax stimulates the bodys natural defences . The vaccine works by causing the body to produce protection against the virus that causes COVID-19. Spikevax uses a substance called messenger ribonucleic acid to carry instructions that cells in the body can use to make the spike protein that is also on the virus. The cells then make antibodies against the spike protein to help fight off the virus. This will help to protect you against COVID-19.
Blood Products Human Immunoglobulin And Timing Of Immunization
NACI recommends that COVID-19 vaccines should not be given simultaneously with monoclonal antibodies or convalescent plasma.
To date, there is insufficient evidence on the receipt of both a COVID-19 vaccine and anti-SARS-CoV-2 monoclonal antibodies or convalescent plasma for treatment or prevention. Therefore, timing of administration and potential interference between these two products are currently unknown. Administration of these products close together may result in decreased effectiveness of a COVID-19 vaccine and/or anti-SARS-CoV-2 monoclonal antibodies because the monoclonal antibodies have high affinity for the spike protein expressed by the vaccines, which could prevent the production of antibodies stimulated by the vaccine.
In the post-exposure setting, expert clinical opinion should be sought on a case-by-case basis when deciding whether anti-SARS-CoV-2 monoclonal antibodies would be appropriate to administer after receipt of COVID-19 vaccine, taking into consideration the risk of exposure and the risk of severe COVID-19 disease in the individual.
To date, there is also insufficient evidence on the receipt of both a COVID-19 vaccine and any monoclonal antibodies or convalescent plasma for treatment or prevention of non-COVID-19 disease. Therefore, timing of administration and potential interference between these two products are currently unknown and expert clinical opinion should be sought on a case-by-case basis.

If I Have Allergies Should I Be Concerned About The Vaccine
While severe allergic reactions, called anaphylaxis, have occurred in the minutes following an injection with the new vaccines, its an extremely rare event. The rate of anaphylaxis has been 11.1 cases per million doses, as of December. By comparison, the rate of severe allergic reaction to the flu shot is about 1.35 cases per million doses. While those statistics may sound scary, severe allergic reactions are a risk with many drugs. Dr. Aaron Carroll, a professor of pediatrics at Indiana University School of Medicine, notes that the risk of anaphylaxis from penicillin drugs is even higher between one in 2,500 and one in 5,000 but that doesnt stop doctors from prescribing them. You can read more from Dr. Carroll about the risks of vaccines here.
All the patients who experienced severe reactions to the vaccines were treated and have recovered. Most of them had a history of anaphylaxis or allergies, but some patients had no known allergies. Every vaccination site is required to have epinephrine and other emergency supplies in case a patient has an allergic reaction. If you have a history of anaphylaxis, youll be monitored for 30 minutes after the shot, instead of the standard 15 minutes.
What Are The Side Effects Of The Second Dose
Sore or red arm Aches Feeling tired
L.A. Public Health emphasized that these milder reactions are both normal and common, and for most people, should go away after two days.
“Your body is learning to build up immunity,” the department explained in a Feb. 4 email. “Having these types of side effects soon after vaccination does NOT mean that you have COVID-19.”
Severe reactions like not being able to breathe are unlikely. But if that does happen, call 911 or immediately head to an emergency room.
