The government is actively considering adopting recommendations made by United States’ Center for Disease Control and Prevention (CDC) that there be longer time intervals between the first and second doses of the Pfizer vaccine for males 12 years and over.
“An 8-week interval may be optimal for some people ages 12 years and older, especially for males ages 12 to 39 years,” the CDC recommends.
The recommendation was made after males developed myocarditis, an inflammation of the heart, after receiving the Pfizer vaccine. The inflammation can reduce the heart’s ability to pump and cause rapid or irregular heart rhythms.
