Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

HPV vaccination may protect against adverse pregnancy outcomes

Having received the human papillomavirus (HPV) vaccine before pregnancy is associated with a lower risk of major pregnancy complications including preterm birth, with the greater reduction in risk seen among women vaccinated at an earlier age, finds a large Swedish study published by The BMJ today.

HPV vaccination linked to lower risk of pregnancy complications

The benefits of the HPV vaccine may extend beyond protection against cancer. In a study published in The BMJ, researchers at Karolinska Institutet found that women who had been vaccinated against HPV were less likely to experience several pregnancy and childbirth complications, particularly preterm birth.
