The news of Booster Shots were a little confusing lately. First, Pfizer stated that it would apply to the authorization of a third covidation, because the data now presents signs ofimmunity of his vaccine after six months. Then, the Food and Drug Administration (FDA) and the disease control and prevention centers (CDC) published a joint statement saying that there is currently no need forCovid booster shot. If you are vaccinated and you wonder how long you are really protected - especially with the very infectiousDelta variant Sweep the country - it's hard not to feel preoccupied with mixed messages.

On July 8, Pfizer cited data from a study in Israel and declared itsEffectiveness of the vaccine "By preventing both infection and symptomatic disease decreased six months after vaccination." The Israeli study, published three days before, concluded that the Pfizer vaccine was effective 64% inInfection Delta variant, 94%,Wall Street newspaper reported. The vaccine has always been very effective in preventing 94% serious disease, 97% by the Israel Ministry of Health.

But while Pfizer believes that these data are reasoned enough to move forward with a third dose of its vaccine within six to 12 months of vaccination, the FDA and the CDC are not yet convinced. In their joint statement, also published on 8 July, the agencies clearly indicated: "Americans who have been completely vaccinated do not need towakeup call At this moment. "They reiterated that existing Covid vaccines are very effective at preventing serious illness and death, even facing the delta variant.

If the FDA and the CDC do not agree with the urgency of Pfizer, however, when do they think that Covid boosters will be needed? There is no clear response from the agencies, although the Joint Declaration stressed that they are "engaged in a rigorous science-based process to be determined whether or when a reminder may be necessary." Meanwhile, experts offered their overview of what needs to happen before getting a third shot.

The Boosters' question arose in the CDC Advisory Committee on the Vaccination Practice Meeting (ACIP) in June, CNN reported. ACIP memberSarah Long, MD, said there were two things that the committee would need to see before believing it was time for people to get another shot. "What we are looking for is at the same time a very neat lookRevolutionary cases And also if there is currently an increase in the elderly - who would be fair enough because they are currently so well controlled, "said a long time.

ACIP memberSharon Frey, MD, shared a feeling similar to the June meeting. "I think the only thing we can do at this time is that we are starting to see a rise in reinfections in people, or new infections among vaccinated people, it's our clue that we need to move quickly" She said, by CNN.

The chronology is still uncertain, but these vaccinating experts agree that if there is an increase in revolutionary cases, it is when you need a Covid shot.William Schaffner, MD, professor at the Vanderbilt University School and Medical Director of the National Foundation of Infectious Diseases, told CNN that we did not currently need boosters, but he also stressed the vulnerable populations, such as 2 to 4% of the American population. It's immunocomized. This group may need another shot earlier given their reduced reduced to the initial vaccine.

Until there is enough an increase in breakthrough cases so that US agencies feel obliged to approve a booster Covid, you may feel worried about your current vaccination status. Most experts, however, say there is no reason for alarm. "Pfizer says we canneed a booster. Call me skeptical, "Ashish k. jha, MD, Dean of the Brown University School of Public Health, tweeted on July 8, while antibody levels decrease over time, "immunity is much more complex. And there is a lot of data than the diet of two strokes working well. "
