"We have direct evidence that fraudulent vaccines... were sold for up to 40,000 pesos (around $2,000) per dose", said Assistant Health Secretary Hugo Lopez-Gatell at a press conference.

Factors associated with this include the effect of different intervals on protection after the second dose, and the risk of infection between doses either due to lower efficacy of a single dose or rapid waning of efficacy while waiting for the second dose.

Any raw images sent back by the rover this week and going forward will also be immediately available to the public on NASA's site. Perseverance had traveled 292 million miles (470 million kilometers) since launching July 30 from Cape Canaveral, Florida.

He added that no private entity had been authorized to purchase COVID-19 vaccines from overseas for commercial purposes and that the shots were only administered by the government free of charge.

Police in northern Mexico arrested six people Wednesday for allegedly trafficking in fake coronavirus vaccines. The scientists compared the number of symptomatic Covid-19 cases in the control and Covid-19 vaccine groups, occurring more than 14 days after the second dose.

The state also announced its allotment of vaccines is increasing, to more than 36,000 doses a week. In addition, antibody levels against the SARS-CoV-2 spike protein remained at similar levels for 3 months.

Professor Pollard said: "It is important to understand whether vaccines can reduce Covid-19 transmission".
