A new outbreak linked to a popular cough-cough vaccine is being traced back to a California woman who died in March from a similar infection.
The California Department of Public Health announced Wednesday that it has linked the coronavirus outbreak in San Diego County to a woman whose death in March was attributed to the coronasavirus vaccine.
Her cause of death was not disclosed.
The woman, who is now 85, had received the vaccine in April but had been tested negative for the virus.
The outbreak was reported in California in March, triggering the state to suspend use of the vaccine.
The state also stopped the use of several other cough-based vaccines, including the flu shot, and said it would re-evaluate its policy to prevent more deaths from the disease.
“The outbreak in California is linked to this California woman, and she had received this vaccine in the past,” Gov.
Jerry Brown said in a statement.
“This case underscores that the vaccine is an effective tool that can protect against these diseases.
It is important to remember that many people are exposed to coronaviruses, so we need to keep our communities safe.”
In May, California reported its first case of coronaviral disease linked to the flu vaccine.
About 4,000 cases have been reported in the U.S. since then, including at least 11 deaths.
The U.N. says the virus has caused the worst pandemic since 1918.
