What we are using now was not a vaccine until they changed the definition of vaccine.

So, how would you describe the Pfizer and Mordena mRNA products?

The previous definitions could have been “interpreted to mean that vaccines were 100% effective, which has never been the case for any vaccine, so the current definition is more transparent, and also describes the ways in which vaccines can be administered,” the spokesperson said.

“It’s also important to note that the modifications to the definition of ‘vaccine’ don’t change the fact that vaccines and the act of vaccination has prevented millions of illnesses and saved countless lives,” the spokesperson said in an email.

There remains the misconception that COVID-19 vaccines were designed to prevent infections altogether, leading people to believe the vaccines aren’t working as they should when they learn about breakthrough infections among the vaccinated.

But the coronavirus vaccines are doing exactly what they were designed to do, which is to prevent severe disease, including the need for hospitalization, and death — even in the presence of more dangerous versions of the virus such as the delta variant.

While data show the coronavirus shots are preventing infections in many outbreak scenarios, the fact breakthrough infections are happening doesn’t suggest failure, experts say.
