- Study: Infectivity and immune escape of the new SARS-CoV-2 variant of interest Lambda “Our results indicate that mutations present in the spike protein of the Lambda variant of interest confer increased infectivity and immune escape from neutralizing antibodies elicited by CoronaVac. These data reinforce the idea that massive vaccination campaigns in countries with high SARS-CoV-2 circulation must be accompanied by strict genomic surveillance allowing the identification of new isolates carrying spike mutations and immunology studies aimed to determine the impact of these mutations in immune escape and vaccines breakthrough.”
- COVID vaccine trials began in March 2020, and then by August 202, we had six strains of the virus.
- After vaccines had been rolled out in the US for eight months, suddenly we were spiking with Delta. Article: Covid cases are rising again in all 50 states across U.S. as delta variant tightens its grip Interesting, now we know that the vaccines wane in efficacy after eight months.
- After multiple vaccine trials, Delta showed up in India and then in 104 more countries, where vaccine trials also took place.
This is a sample of just a few of the major trials happening around the world and how cases and variants were impacted:
And this is what India’s situation with the Delta variant looked like:
For a little humor to lighten the subject:
