Vaccine allergy

Vaccinations prevent 2 million to 3 million deaths annually, and 1.5 million more could be avoided with better coverage.1 Vaccinations are safe, and allergic reactions are extremely rare. In the United Kingdom, only 1 case of anaphylaxis or anaphylactoid reaction per million vaccine doses was reported between 1997 and 2003 (with no fatalities).2 However, poor understanding of common and expected adverse effects often leads to misdiagnosis. No large studies using supervised single- or split-dose or multistep administration (gold standard in drug allergy workup) have been published.
