Will you need a COVID booster? Some say yes. But the CDC says not yet.

With the increasing incidence of delta forms, how can you protect yourself from the prevalent strain of COVID-19? Here's what to know about the discussion about vaccine boosters.

With the Delta variant of the coronavirus becoming the dominant strain in the United States, pharmaceutical giant Pfizer said it is working on a booster dose of its COVID-19 vaccine. Vaccine experts in Britain say a booster dose may be needed before winter. A new third dose could target the highly contagious delta mutation, which has spread to 100 countries and is responsible for growing new infections in the United States.

In a recent press release, Pfizer said that the third shot of its vaccine would boost immunity for those who have already received the first two doses of the vaccine. In addition to creating a booster for the current vaccine, the drug company said it would formulate a new version of the COVID-19 vaccine to target the delta variant. 

Earlier this month, the CDC and the World Health Organization issued contradictory guidance that fully vaccinated people to wear face masks. This debate, along with the ongoing discussion of booster shots, underscores how scientists and other health experts continue to deal with the uncertainties of COVID-19 as restrictions ease. Here's what we know about Pfizer's booster plans and why (CDC) and the Food and Drug Administration (FDA) are warning against it, at least for now.
