The DTaP and Tdap vaccines both protect against three bacterial infections: diphtheria, tetanus and pertussis, whereas the Td vaccine only protects against diphtheria and tetanus. In addition, the vaccines vary in terms of who should receive them and the quantities of vaccine proteins they contain: 1  DTaP: The DTaP vaccine is given to infants and young children in a series of five shots â at 2 months, 4 months, 6 months, 15 to 18 months, and again at 4 to 6 years of age. Tdap: The Tdap vaccine is different from the DTaP vaccine because it contains lesser quantities of diphtheria and pertussis proteins.
1 To prevent a heart attack, take two low-dose (81 mg) aspirin every day if youâre at risk or over 40.  If you think youâre having a heart attack, take 325 mg of aspirin, and make sure to chew the aspirin before swallowing, because it gets into the bloodstream quicker.
Your doctor will discuss what dose is right for you. Very low doses of aspirin â75 milligrams (mg), which is less than a standard baby aspirin â can be effective.Your doctor will usually prescribe a daily dose anywhere from 81 mg â the amount in a baby aspirin â to 325 mg (a regular strength tablet).If you have had a heart attack or have had a heart stent placed, it's very important to take aspirin and any other blood-thinning medications exactly as recommended.he benefit of daily aspirin therapy doesn't outweigh the risk of bleeding in people with a low risk of heart attacks. The higher your risk of heart attack, the more likely it is that the benefits of daily aspirin outweigh the risk of bleeding.
