– A female nurse in her 40s who was vaccinated against a novel coronavirus infection (Corona 19) in the United States was confirmed to be corona 19 after vaccination, ABC News reported on the 29th (local time). It seems to be an example showing that personal quarantine is still needed to prevent infection with COVID-19 until antibodies are formed after vaccination.
According to the media, the nurse is 45 years old and works in an emergency room in San Diego, California. On the 18th, I received the Corona 19 vaccine developed by Pfizer. At the time of vaccination, the media reported that he experienced a side effect of feeling pain in his arm. Six days later, the nurse, who was working in the Corona 19-related department, felt chills and muscle aches and fatigue, and was diagnosed with infection after being tested for Corona 19.
In the nurse’s case, Christian Ramas, a professor at San Diego State University’s School of Public Health, pointed out that it may take days for antibodies to form after vaccination. He told ABC News, “In clinical trials of the vaccine, it took about 10 to 14 days for the antibody to be produced. Even after this period, a second vaccination is needed to be fully protected.”
According to the clinical results of Pfizer’s vaccine released on the 8th by the US Food and Drug Administration (FDA), the Pfizer vaccine is effective about 10 days after vaccination. 52% after the first vaccination and 95% after the second vaccination. As a side effect, it was found that about 84% of clinical participants felt pain in the area where they received the vaccination.
Another possibility is also being raised as to the reason why he was diagnosed with Corona 19 after vaccination. It is speculated that the symptoms would have appeared after the incubation period had already passed before the vaccine was given.
“Both potential scenarios remind us that vaccines are not a panacea,” ABC News said. “To prevent an epidemic, it takes time, and you have to stick to habits such as masks and hand washing.”
