What revolutionary vaccine technology teaches cells to produce their own spike protein?
Answer
mRNA vaccine
mRNA vaccines work by delivering genetic instructions (mRNA) that teach cells to produce a specific viral protein—typically the spike protein on the virus surface. The cell machinery translates the mRNA to create the harmless spike protein, which triggers immune recognition and antibody production without any actual virus being present. After the protein is made, cells break down the mRNA and remove it as waste. Pfizer and Moderna's COVID-19 vaccines achieved 95% efficacy using this groundbreaking approach.
💡 Did you know?
mRNA vaccines were developed in just 300 days during 2020—previously, vaccine development took 5-10 years.
