Pharmaceuticals Pfizer and BioNTech reported that their COVID-19 vaccine remains highly effective for at least six months after the second dose is administered and that it also works against the South African variant of the virus. The findings come from a follow-up of volunteers who participated in the vaccine trials, which so far still show no major safety issues, the companies said in a statement.
However, the delays in vaccinations, the fatigue of many societies in the face of restrictions and the most contagious variants of the coronavirus have led the world to a fourth wave of COVID-19, with figures already resembling the third in late 2020, so far the worst in infections and deaths.
According to figures from the World Health Organization, global cases today exceed 127 million, while deaths are close to 2.8 million, and both infections and weekly deaths continue to rise after the hopeful decline in the curve that existed from the beginning of 2021 until the middle of February. However, experts warn that, as happened in mid-2020, a decrease in the average age of the most serious cases is again being noticed, and the number of people between 30 and 60 years old who require emergency interventions is increasing.
The World Health Organization warns that vaccination should not for now replace the preventive measures in force since last year, such as physical distancing, hand hygiene, avoiding crowded places and the use of a mask in good condition, such as the KN95 with valve.
