American President Joe Biden has weighed in after Sesame Street’s Big Bird was accused of spreading “propaganda” by a Texas senator after the cartoon muppet announced it had been vaccinated against COVID-19.

It follows the US’s approval of the Pfizer vaccine for five- to 11-year-olds.

Writing on Twitter, the giant yellow bird – who is eternally six years old – said: “I got the COVID-19 vaccine today! My wing is feeling a little sore, but it’ll give my body an extra protective boost that keeps me and others healthy.

“Ms. @EricaRHill even said I’ve been getting vaccines since I was a little bird. I had no idea!”

However, Senator Ted Cruz – who is vaccinated, and has previously said “I believe in vaccines” – responded with: “Government propaganda … for your 5 year old!”

However, President Joe congratulated the Sesame Street resident and said: “Good on ya, @BigBird. Getting vaccinated is the best way to keep your whole neighborhood safe.”

A number of American rightwingers had piled in after Senator Cruz tweeted, with Steve Cortes, a host on the conservative Newsmax network, adding: “This kind of propaganda is actually evil.”

Lisa Boothe, a Fox News contributor, accused the television animal of “brainwashing children who are not at risk of COVID.”
