NEW YORK (CBSNewYork) – The vaccination didn’t stop a Brooklyn woman from contracting COVID-19.

While there is concern and confusion about the COVID vaccine, experts say there are a number of reasons someone can become infected after being shot.

Ashley Allen, like millions of others, now has a vaccination card. She got the Johnson & Johnson shot on March 10th.

“This is just the vaccine I wanted to make. Seemed easy. One shot and it’s done, ”Allen, 31, told Jenna DeAngelis of CBS2.

Allen said it was easy, although symptoms had been common for 24 hours.

Three weeks later, she had a cough and fatigue that she thought was Lyme disease after spending some time in the backcountry.

“I didn’t think about COVID at all,” said Allen.

Two rapid tests and a PCR confirmed that it was the coronavirus.

“I just couldn’t even believe it,” said Allen.

She was particularly surprised because she continued to use safety precautions, such as wearing a mask, after she was shot.

“Just because you have a vaccine doesn’t mean you can’t wear it and give it to other people,” Allen said.

“So did you still take the same precautions before and after vaccination?” DeAngelis asked.

“Yeah, I never had a question on my mind,” replied Allen.

Allen is among the scattered reports of “breakthrough” cases – fully vaccinated people still getting infected.

This doesn’t just apply to COVID vaccines.

“No vaccine is 100% effective or effective,” said Dr. Anthony Fauci.

According to Dr. It can happen to Fauci if:

  • The vaccine itself is ineffective or has been improperly stored.
  • A person has a poor immune response.
  • A new variety is circulating.

“There were essentially no deaths or hospitalizations among the vaccinated,” said Dr. Fauci.

The CDC chief said if you get a vaccine it could be two to six weeks before it is fully protected.

Allen believes her shot likely made all the difference in the severity of her illness.

“I would like to imagine that it definitely played a role,” she said. “So I’m pro-vaccine. Take care of yourself and take care of the people around you. “

While she dealt with COVID, Allen was in the process of opening a new business based on her passion for plants, which she discovered while she was temporarily absent from her real job.
