(WHTM) — Pfizer and Moderna are both saying that those who are vaccinated may need booster shots as soon as September.

That would apply to those who got vaccinated first.

Experts believe additional booster shots would be necessary in mid to late April with data pointing to one extra shot, not two.

Studies have shown that both the Pfizer and Moderna vaccines remain effective six months after they’re administered.

On April 13, Moderna said its vaccine’s efficacy was found to be greater than 90% against all COVID-19 cases and greater than 95% against severe cases of the virus.

Pfizer released data on April 1 showing that its mRNA vaccine is highly effective six months after the second dose.

But Pfizer CEO Albert Bourla told CBNC’s Bertha Coombs that people will “likely” require a third dose of a COVID-19 vaccination within 12 months of being fully vaccinated.

States across the country have begun to dismiss mask mandates for qualifying individuals as vaccination rates continue to inch higher.

“It is getting to the point to where by the 4th of July we might be able to declare this thing over,” said Boston College public health expert Dr. Philip J. Landrigan.
