State Rep. Alma Hernandez, a Democrat, said on April 28 that despite taking all precautions and getting the vaccine 11 weeks ago, she still tested positive for COVID-19, which is caused by the virus.
She noted that her symptoms are “pretty mild.”
“I will quarantine in my Phoenix home until next Wednesday and I encourage all of you to take this seriously and continuing practicing COVID protocols,” she added.
“These are called ‘vaccine breakthrough cases,’“ the statement says. ”This means that while people who have been vaccinated are much less likely to get sick, it may still happen. Experts continue to study how common these cases are.”
The CDC says that no vaccine works 100 percent of the time and there are breakthrough cases with all vaccines. It is possible for a small percentage of the people who have been vaccinated to still develop symptoms, be hospitalized, and even die from the infection. It is also possible for a fully vaccinated person to end up being positive but asymptomatic.
CDC officials also say that people can get infected before the vaccine has a chance to take full effect, about two weeks after the second dose. In addition, new variants may infect a fully vaccinated person. The agency said it is monitoring breakthrough cases to see if there are any patterns in how the virus infects fully vaccinated people.
“We expect such rare cases, but so far out of more than 84 million people who are fully vaccinated, we have only received reports of less than 6,000 breakthrough cases,“ said CDC Director Dr. Rochelle Walensky. ”Although this number is from 43 states and territories and likely an underestimate, it still makes a really important point: these vaccines are working.”
Walensky said that even in breakthrough cases, the vaccines help prevent serious illness and protects against variants.
