USA: At least 125,000 vaccine breakthrough infections, 1,400 dead

At least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died, according to data collected by NBC News.  The total number of breakthrough cases is likely higher than 125,683, since nine states, including Pennsylvania and Missouri, did not provide any information, while 11, like Florida, did not provide death and hospitalization totals. Four states gave death and hospitalization numbers, but not the full tally of cases.

Detection of 54 cases of the P.1 variant in Massachusetts in less than a month

All three global VoCs (B.1.1.7, B.1.351, and P.1) have now been detected in MA. However, unlike B.1.1.7 and B.1.351, P.1 has shown a rapid rise in frequency in the few weeks following its first detection on March 16th, 2021.  Phylogenetic analysis of these 54 P.1 genomes from MA, alongside four additional P.1 genomes from neighbouring states (two from Connecticut (CT) and one each from Maine (ME) and Rhode Island (RI)) and 895 other global P.1 sequences from GISAID, 6 1 suggests at least six introductions of P.1 into MA and at least eight introductions of P.1 into the New England region, likely from both international and domestic sources.
