Hepatitis B is a serious disease. A company has a new hepatitis vaccine that induces hepatitis antibodies more vigorously than existing vaccines and does so after 2 doses (instead of the usual 3). The vaccine works through a unique adjuvant.
In the latest trial to examine effectiveness of the drug, heart attack risk was higher in the vaccine group. Vaccination and heart attack risk may not come as a surprise to you. The stated purpose of a vaccine is to invoke an immune response. The immune response is linked to inflammation, oxidative stress, and immune cell activation. All three are linked to heart attack risk.
What is Hep B?
Hepatitis B is a viral infection contracted from blood to blood contact.
HBV is transmitted through activities that involve percutaneous (i.e., puncture through the skin) or mucosal contact with infectious blood or body fluids (e.g., semen, saliva), including
· Sex with an infected partner
· Injection drug use that involves sharing needles, syringes, or drug-preparation equipment
· Needle sticks or sharp instrument exposures
· Sharing items such as razors or toothbrushes with an infected person
HBV is not spread through food or water, sharing eating utensils, breastfeeding, hugging, kissing, hand holding, coughing, or sneezing.
