Pharmaceutical company Pfizer reported that tests of its vaccine against Covid 19 in children aged 2 to 5 years showed that it did not provide the expected immunity.
It therefore recommends taking a third dose. The study found that two doses of the Pfizer / BioNtech vaccine adapted for children did not produce the expected immunity in children aged 2 to 5 years, although this was the case for infants up to 2 years , reports CNN.
Therefore, after analyzing the data, the company decided to include a third dose for all children and infants aged 6 months to 5 years in its vaccine testing program.
“Clinical studies will now include an evaluation of the effectiveness of the third dose of 3 micrograms, which will be given at least two months after taking the second dose to ensure a high level of protection in this age group.“, The company announced. Pfizer will also test the effectiveness of the third dose in older children, 5 to 11 years old and 12 to 15 years old.
