Some children may have a bad reaction to the pertussis vaccine in DTaP and should not take another dose. There is, however, a vaccine called DT that will protect them from diphtheria and tetanus. Talk with your doctor if your child experienced any of the following reactions:
The current price for a forever stamp is .44 cents (2010) so 20 years from now the value of that same stamp will still be .44 cents, even if the price for one ounce is $2 then. So, you would need five forever stamps from this year for 1 ounce in 20 years.
So if you buy a Forever Stamp at $0.49 cents per stamp and the first-class postage rate rises in six months to $0.55 per stamp, you are saving $0.06 cents for every letter you send. If you assume postal rates will always rise and never sink, then Forever Stamps are a good investment.
