There’s no evidence you need a COVID-19 vaccine booster shot ... yet

The coronavirus vaccine has been in our lives for close to seven months now. And, according to a group working with the Centers for Disease Control and Prevention, there’s no evidence we need a booster shot to keep immunity to COVID-19.

The group said, however, that the need for a booster shot — a third shot for those with Moderna/Pfizer vaccines, or a second shot for those who got Johnson & Johnson — could become necessary down the road, NBC News reports.

There are some serious questions health officials will need to answer — how do unvaccinated people impact the need for a booster? Should the country help the entire world get vaccinated before offering third shots to people?

  • “Prior to going around and giving everyone boosters, we need to improve the overall vaccination rate,” said Dr. Keipp Talbot, an associate professor of medicine at Vanderbilt University, according to NBC News.

Dr. Sharon Frey, clinical director of the Center for Vaccine Development at Saint Louis University Medical School, told NBC News we’d know if we needed a new booster shot if there are rising COVID-19 cases among fully vaccinated people.

  • “I think the only thing we can do at this moment is, if we start to see an uptick in reinfection in people, or new infections in people who have been vaccinated, that’s our clue that we need to move quickly,” Frey said.

More recently, Matt Hancock, the U.K.’s health secretary, said the U.K. is experimenting with plans for how to distribute the third COVID-19 booster shots, as I wrote for the Deseret News. Experts are waiting to see if it’s possible to mix-and-match vaccine types before unleashing the plans.

  • “We are currently trialing which combinations of jabs are the most effective,” Hancock told BBC News.
  • “In the next few weeks, when we get the clinical data through on what’s the most effective combinations to have … then we’ll set out all the details for the booster programme for the autumn.”

Some companies have their eyes on the fall for booster shots. Moderna and Pfizer, who both developed the common two-dose COVID-19 vaccines, told Axios that the “booster” COVID-19 shots will likely be needed by fall 2021.
