The proteins and mRNA disappear from the body in a matter of days. The person’s immune system will then recognise these proteins as foreign, produce antibodies, and activate T cells (white blood cells) to attack them.
When vaccinated with the bivalent shot, some of a person’s cells will read the mRNA instructions and temporarily produce the spike proteins of both variants. Remember to submit your COVID-19 immunization form after your final dose. The mRNA molecule has instructions for making the spike proteins of both variants, and spike proteins on the coronavirus surface allow it to enter human cells. Our goal is to aim for the stars and have 100 of our staff immunized. The vaccine cocktail works by preparing the body to defend itself against both coronavirus strains. The pioneering messenger RNA booster shot contains mRNA-1273 - the original Spikevax - and a vaccine candidate which targets the Omicron variant of concern.
#Vaccine infographic trial
In June, Boston-based Moderna reported that trial data showed that when given as a fourth dose, the two-strain vaccine raised virus-neutralising antibodies by eight-fold against Omicron. The Medicines and Healthcare products Regulatory Authority based its decision on clinical trial data that showed the booster triggered “a strong immune response” against the BA.1 Omicron variant and the original virus. For children receiving Pfizer-BioNTech vaccine who turn 4 to 5 years old during their 3 dose vaccine series and for children receiving Moderna vaccine who. drug company Moderna’s variant-adapted vaccine for the country’s booster campaign starting September.
