Big Bird, the beloved Sesame Street character, tweeted on Saturday that he received his COVID-19 shot

The tweet sparked criticism from some conservatives, like Texas Sen. Ted Cruz who called it 'government propaganda for your 5 year old'

The Texas Senator was soon facing backlash online, himself, for his criticism of Big Bird's vaccine, with some claiming he was spreading false information

The controversy comes just days after the Centers for Disease Control authorized the use of the Pfizer vaccine for children ages five to 11

The decision has become controversial with studies showing children are less likely to get severe COVID symptoms

 Studies also show that the vaccine can cause myocarditis in young children 

As a result, many parents are hesitant to give their children the vaccine
