An annual covid-19 vaccination in the same vein as the yearly flu vaccine is also being reviewed.
This fall, you may be able to get a second covid-19 booster shot along with your annual flu vaccine.The U.S. Food and Drug Administration has begun reviewing data to decide whether to authorize a second booster dose of the messenger RNA vaccines from Pfizer and partner BioNTech and from Moderna,According to the Journal’s report, regulators are also weighing whether this fourth booster could be the start of an annual covid-19 vaccination.
Planning is still in the early stages, and several issues would need to be resolved before health regulators moved forward with the process. Authorization would depend on determinations as to whether the second booster should be authorized for all adults or limited to certain high-risk populations such as the elderly, as well as whether another booster dose should target the Omicron variant or be formulated differently, one of the people familiar with the matter told the Journal.
Among other data, ongoing research would need to show that a fourth dose significantly improved people’s immune defenses that have waned in the months following the first booster and would reduce their risk of developing symptomatic and severe health issues from the virus. Researchers have also been debating whether a fourth dose would be necessary to protect against Omicron and any new, highly transmissible coronavirus variants that may emerge down the line, the Journal reports.
