Spanish nurse contracted coronavirus after vaccination with Pfizer and BioNTech vaccine

Despite all the adversity that happened in 2020year, in December in Russia, the United States and other European countries, vaccination against COVID-19 started. At the same time, the only drug approved by the EU regulatory authorities, as in the United States, is a joint development of the American Pfizer and the German BioNTech. In our country, vaccination against the new coronavirus infection with Sputnik V began on December 5. The only thing that unites Russia and Western countries is the vaccination of the most at-risk populations. So, in Moscow, employees of medical and educational institutions and city social services, both public and private, aged 18 to 60, can receive the vaccine. In turn, in the US and the EU, people over 70 and even 80 years old can receive the vaccine: recently, 89-year-old Spanish resident Joseph Perez received the first injection. But the most interesting news came quite recently: it turned out that a nurse at a nursing home for the elderly was vaccinated but still fell ill with COVID-19. We tell you what is known about this and two other similar cases.

Vaccination against coronavirus in the world

At the time of this writing, the numberreported cases of COVID-19 have exceeded 82 million, and according to Johns Hopkins University, the disease has claimed the lives of about 1.7 million people. Given the number of new cases of infection with the new, more infectious strain of the coronavirus SARS-CoV-2, more and more countries are fencing off from the UK, on ​​the eve of announcing a new tough lockdown.

At the same time the total number of infected in Russia has reached 3,131,550 (over 2.1% of the population), told reportersof the TASS news agency on Wednesday at the operational headquarters for the fight against coronavirus. Thus, our country ranks fourth in the number of registered cases of COVID-19 in the world. The US continues to lead the list, with a record 20 million cases; the second and third places are occupied by India and Brazil with 10 and 7 million cases, respectively.

The speed of vaccine development and the start of vaccination one year after the first reported case is unprecedented.

But the good news in this whole story, fortunately, is a massive coronavirus vaccination that is being rolled out around the world. At the end of 2020 There are several COVID-19 vaccines registered in the world: two vaccines are registered in Russia:"Sputnik V" and "EpiVacCorona", and on December 5 in Moscow, vaccination against coronavirus with the drug "Sputnik V" started. In the United States and Great Britain, the population began to be inoculated with the drug from Pfizer / BioNTech. In addition, the drug developed by Moderna was approved in the country, and the British pharmaceutical company AstraZeneca announced the beginning of clinical trials of a combination of its AZD1222 vaccine. But how effective are these vaccines and can you get SARS-CoV-2 after being vaccinated?

Can I get sick after vaccination?

Recently, the world media reported at once about two similarcases of infection with a new coronavirus after vaccination. According to the Spanish El Pais, the results of the PCR test for SARS-CoV-2 of the nurse who received the vaccination showed a positive result. Sources in the health department indicate that the risk of infection for the elderly residents of the boarding house is minimal, however, the elderly were preventively isolated.

The second case of infection with the new coronavirusinfection after vaccination with vaccines from Pfizer and BioNTech has been registered in the United States. An ambulance nurse in the California city of San Diego tested positive for the coronavirus just days after being vaccinated against the disease, according to US media reports.

The incubation period for a new coronavirus infection can be up to 14 days.

The third person tested for coronavirustested positive for a 45-year-old nurse from the United States who received the first dose of the vaccine prepared by Pfizer and BioNTech. As the victim himself admitted to KGTV, an affiliate of ABC News, the only side effect he faced after being vaccinated was pain in his arm. However, six days later, a nurse was hospitalized with symptoms of COVID-19.

According to experts interviewed by journalists, these cases are not “unexpected”because those who have recently been vaccinated have not fully developed the immunity that protects against COVID-19.

Immunization in two stages

Pzifer and BioNTech vaccine clinical trialsshowed that immunization of the vaccinated (which, according to the manufacturers, is effective in 95% of cases), can be achieved a few days after receiving the second dose of the drug, which in the case of Pzifer takes about 21 days, as in the case of the Russian vaccine Sputnik-V ". For more information on why the Russian vaccine is called Sputnik-V, read the article by my colleague Ramis Ganiev.

According to experts interviewed by journalists,Post-vaccination infections among healthcare workers are another reminder that vaccines are not a panacea and that defeating a pandemic will take time. This is why it is important to continue to adhere to the recommendations of the World Health Organization (WHO) - wear a mask, wash your hands and follow social distancing guidelines. Be healthy.
