Dr Anthony Fauci, President Joe Biden’s chief medical adviser, has recently said that COVID-19 vaccines for children under the age of 12 would be available before Halloween.
"There is really a good chance it will be available before the October 31 holiday," Fauci said, as quoted by Bloomberg.
Fauci further said that he will be in favour of schools making COVID-19 vaccine compulsory once they get full approval.

His comments came after Pfizer and BioNTech said that its COVID-19 vaccine works for children ages 5 to 11 and that it will seek US authorisation for this age group soon.
The vaccine made by Pfizer and its German partner BioNTech already is available for anyone 12 and older.
In participants five to 11 years of age, the vaccine was safe, well-tolerated and showed robust neutralising antibody responses," US giant Pfizer and its German partner said in a joint statement.
They plan to submit their data to regulatory bodies in the European Union, the United States and around the world "as soon as possible".
The trial results are the first of their kind for children under 12, with a Moderna trial for six-11 year olds still ongoing.
Although children are considered less at risk of severe Covid, there are concerns that the highly contagious Delta variant could lead to more serious cases.
For kids, Pfizer tested a much lower does — a third of the amount that’s in each shot given now.
Kids in the 5-11 age trial group received a two-dose regimen of 10 microgrammes in the trial, compared with 30 microgrammes for older age groups, the companies said. The shots were given 21 days apart.
The side effects were "generally comparable to those observed in participants 16 to 25 years of age", it added.
