COVID-19 and Summer 2022: Accelerate Now or Better to Wait?

July 5, 2022 – Nov combination vaccinefor COVID-19 will likely be released this fall, offering more protection against Omicron variants of COVID-19. Vaccine maker Moderna said in recent news exemption that the new vaccine expected to be a “leading candidate” as well as a booster in the fall. But neither CDC doubled down on its recommendations for those eligible to get their second booster, some are questioning the timing and choice of their fourth shot.

Here are answers to some frequently asked questions about boosters.

Should I get a second booster if I recently tested positive for COVID-19?

According to CDC recommendations, it is best to wait until your symptoms are gone before receiving a second booster shot. The CDC says some may consider waiting 3 months after the onset of COVID-19 symptoms to get a second booster shot, but the only requirement is that you are no longer self-isolating.

Should I expect different side effects from the second booster?

Hannah Newman, director of infection prevention at Lenox Hill Hospital in New York, says side effects from a second booster vary from person to person. “The side effects are very short-lived and can be treated with supportive medications,” she says. According to experts in Johns Hopkins Medicine, common side effects of COVID-19 vaccinations include fever, body aches, chillsand swollen lymph nodes. But these symptoms are a sign that “your immune system answers the shots,” they say

Should I try to time my second booster dose with the expected spike in COVID-19 cases in the fall?

Newman recommends getting the second booster as soon as possible. “There’s a high level of transmission in the community right now, so it’s better to get it as soon as you’re eligible so you have time to build antibodies.”

Amesh Adalya, MD, assistant professor at Johns Hopkins University’s Bloomberg School of Public Health, says it takes “probably about 7 days until you reach maximum protection for the immune system to respond.”

Should immunocompromised people consider getting a second booster?

The FDA has authorized second booster shots for anyone over age 50 and people over age 12 who are immunocompromised. Newman says the second booster could offer immunocompromised people more protection from COVID-19. “If they end up with a sudden infection, that would ensure that their symptoms would be milder in theory,” she says.

How does the new Novavax vaccine affect COVID-19 vaccinations and boosters?

A panel of advisors to the FDA says Novavax A vaccine against COVID-19 must receive emergency use authorization, although the agency itself has not yet given consent. Novavax vaccines are protein-based vaccines, which means they inject the spike protein of the COVID-19 virus into your body. Protein vaccines have been used for decades. Common vaccines such as those for hepatitis B and human papillomavirus (HPV) use this method. They’re different from Moderna and Pfizer’s mRNA-based vaccines, which instruct your body to produce the peak protein so your immune system can learn to recognize it in the future.

William Schaffner, MD, professor of preventive medicine at Vanderbilt University School of Medicine, says unvaccinated Americans may be more likely to get the Novavax vaccine if they are skeptical of mRNA vaccines, saying that “Novavax is made from -traditional methods, so we can add more people to the vaccinated group.”

If I have three doses of the Pfizer vaccine, can I switch to Moderna for the fourth?

You can get a different second booster that is different from the main series and the first booster you received. Survey sponsored by National Institutes of Health found that the use of different vaccines as a first booster was safe and effective.

I expect

Much may depend on whether the combination vaccine is designed to target both coronavirus strains in one product received FDA clearance and CDC recommendations for use as an updated booster.

Meanwhile, Dr. Ashish Jha, coordinator of the White House’s COVID-19 response team, assured reporters during a June 23 White House briefing that there will be enough of this combination — known as the bivalent vaccine — for high-risk Americans. which enter autumn and winter. But he said that without new funding for COVID-19 from Congress, “we will not have enough vaccines for every American who wants one.”
