KOMPAS.com - US regulators on Tuesday, May 17 authorized a Covid-19 booster shot for healthy 5- to 11-year-olds, hoping an extra vaccine dose will enhance their protection as infections once again creep upward.
Everyone 12 and older already was supposed to get one booster dose for the best protection against the newest coronavirus variants — and some people, including those 50 and older, can choose a second booster.
The Food and Drug Administration's authorization now opens the third shot of Pfizer's vaccine to elementary-age kids, too — at least five months after their last dose.
There is one more hurdle: The Centers for Disease Control and Prevention (CDC) must decide whether to formally recommend the booster for this age group. The CDC's scientific advisers are scheduled to meet on Thursday, May 19.

Pfizer and its partner BioNTech make the only Covid-19 vaccine available for children of any age in the US. Those ages 5 to 11 receive one-third of the dose given to everyone 12 and older.
Whether elementary-age children need a booster has been overshadowed by parents' outcry to vaccinate even younger tots, those under 5 — the only group not yet eligible in the US. Both Pfizer and rival Moderna have been studying their shots in the youngest children, and the FDA is expected to evaluate data from one or both companies sometime next month.
For the 5- to 11-year-olds, it's not clear how much demand there will be for boosters. Only about 30 percent of that age group have had the initial two Pfizer doses since vaccinations opened to them in November.
But Pfizer's vaccine "is effective in helping to prevent the most severe consequences of Covid-19 in individuals 5 years of age and older," said FDA vaccine chief Dr. Peter Marks "A booster dose can help provide continued protection against Covid-19 in this and older age groups."
In a small study, Pfizer found a booster revved up those kids' levels of virus-fighting antibodies — including those able to fight the super-contagious omicron variant — the same kind of jump adults get from an extra shot.
