During a press briefing on July 13,Jay Butler, Assistant Director CDC, warned that the existing data showed that the second shot of a two-dose plan was statistically when side effects were most likely to develop, warning that more data were needed to ensure a reminder. nopotentially dangerous situation. "We are delighted to know if a third dose can be associated with a higher risk of adverse reactions, especially some of these more serious effects, although very rare," he said.

Butler added that, if the need for a booster may not put pressure for the general population, he believes that those more susceptible to the virus, such as theseniors or other high-risk people, would be most likely to demand the shots, Reuters reports.

"

Nevertheless, other experts pointed out that thanks to the variant of Delta, the most pressing question at the moment could actually beGet the first shot rather than push for a third party.
