In the Czech Republic, 4.4 million first doses and 2 million second doses have been administered since the beginning of vaccination last December.
–
The vast majority of people received the Pfizer / BioNTech vaccine, which received 5.2 million doses. The second most common vaccine, albeit significantly apart, is AstraZeneca with 632,000 doses, equivalent to about 300,000 people.
–
Modernity was vaccinated with 578 thousand doses and a single-dose vaccine from the American company Johnson and Johnson was given to 66 thousand people. All other vaccines are two-dose.
–
The highest protection should be provided by modern mRNA vaccines, ie Pfizer and Moderna, whose efficacy is around 94 percent.
–
The efficacy of the AstraZeneca vector vaccine, with a first and second dose interval of three months, ranges from 76 to 82 percent. The lowest efficacy is reported by a single-dose Johnson and Johnson, at 66 percent.
–
AlstraZeneca, which is vaccinated by general practitioners in the Czech Republic, has been the most discussed since its approval by the European Medicines Agency (EMA). Experts are debating whether it is effective against newly discovered, more contagious mutations.
–
It is also not clear in which age groups the population will use it. Some countries refuse to give the vaccine to the elderly, some have even stopped using it.
–
For example, Germany or Switzerland refused to give the vaccine to people over the age of 55 because few people in these age groups were represented in clinical trials.
–
In addition, according to Hana Cabrnochová, vice-chairwoman of the committee of the Czech Vaccine Society, the European Union will probably no longer buy AstraZenek centrally in the future.
–
So far, the last problem that may be related to AstraZenka is data from the English Office of Public Health England (PHE).
–
According to him, a third of the dead British people infected with the Indian mutation were completely vaccinated. In the United Kingdom, 70 percent of the population received AstraZenek. According to the Authority, there is uncertainty about the extent of the effectiveness of the vaccine after two doses.
–
However, immunologist Václav Hořejší from the Academy of Sciences of the Czech Republic pointed out that although the reported efficacy of vaccines is different, vaccines provide different protection against infection, against serious processes and possible death in a relatively high percentage.
