A San Diego nurse who received the Pfizer vaccine during the initial rollout was diagnosed with Kovid-19 infection on December 26, more than a week earlier.
News from ABC10 A nurse named Matthew W works as an emergency room attendant at two different Southern California hospitals and only noted that his hand was sore after being vaccinated but had no other side effects.
Then, the day before Christmas, after a change to the Covid-19 unit, Matthew fell ill, with symptoms including a cold, muscle aches and fatigue.
On December 26, he tested positive for COVID-19.
Despite the disappointment, this result is not unexpected among public health experts.
“It’s not any kind of unpredictability. If you work through the numbers, this is what you’d expect if someone reveals it,” Christian Ramers, an infectious disease specialist at the Family Health Center in San Diego, told reporters.
Rammers also noted that Matthew was infected before the vaccine was given, and that the symptom began after he was vaccinated.
He added, “We know from clinical trials of the vaccine that it will take you 10 to 14 days to start vaccination protection.”
At the time, Matthew received only one dose of the vaccine. The Pfizer vaccine is made up of two different vaccines, which are given intravenously Except for three weeks.
Documents U.S. for disease control and prevention. A single dose of the Pfizer vaccine, issued by the centers, shows an average 88.9 percent efficacy rate for preventing infection. The researchers noted that the lack of data available for results with participants who received only a single dose of the vaccine could not support any conclusions on the effectiveness of a single dose of the vaccine “because both participants in the clinical trial received both doses.”
Rammers says the effectiveness rate after the first dose of the vaccine is around 50 percent, and the second dose gives a 95 percent effectiveness against the virus.
“You’ve heard that health professionals are very optimistic about the beginning of its end, but it will be a slow roll as we roll out the vaccine for weeks to months.”
