December 30th – An emergency nurse in the United States was still diagnosed six days later after being vaccinated against the novel coronavirus on the 18th.

Infectious disease experts say that the vaccine will not appear protective immediately, and it will take at least 10 to 14 days to be effective.

According to an ABC report on the 28th, Matthew W., a 45-year-old male nurse in the emergency room in San Diego, California, USA. Pfizer was vaccinated against the novel coronavirus on December 18.

At that time, the only side effects were sore arm muscles. Unexpectedly, Matthew had chills, systemic muscle pain and fatigue six days later. After testing, he was diagnosed with COVID-19.

Matthew is not the only case that has been diagnosed after vaccination. Christian Ramers, an infectious disease specialist at the San Diego Family Health Center, said he was aware of several other cases in the San Diego area that were still confirmed by health care workers after vaccination, saying it showed that the vaccine’s results were not immediate and that the vaccine did not provide comprehensive protection.

Ramos said that this situation is not surprising, because it will take about 10 to 14 days to have a protective effect after vaccination, and a second dose of the vaccine will be required. “The protection of the first injection is about 50%, and the second dose will be increased to 95%.”

In addition, the incubation period of COVID-19 is long, and Matthew may have been infected long before vaccination. “All this represents that while the vaccine is beginning to end the pandemic, people must adhere to basic public health guidelines,” Ramos said.

“In short, wearing masks, washing hands and social distancing are the most important measures to prevent the epidemic.”

On December 14, the United States began to use the coronavirus vaccine jointly developed by Pfizer and BioNTech.

To date, about 2.1 million people across the United States have reportedly been vaccinated against the novel coronavirus produced by Pfizer.
