In Britain people are now being warned *not* to get their second dose at 3 or 4 weeks because this offers less protection than waiting 8 weeks or longer.
Warnings over the lack of long-term protection offered by jab intervals shorter than eight weeks come as scores of under 40s continue to receive second doses early at walk-in clinics, contrary to Government guidance.
…“There is very good immunological and vaccine effectiveness evidence that the longer you leave that second dose the better for Pfizer and eight weeks seems to be a reasonable compromise.”
Professor Harnden emphasised that “you’re definitely less protected against asymptomatic disease if you have a shorter dose interval”.
I’m so old I can remember when first doses first wasn’t “following the science.”
