There is often cross-sensitivity and cross-resistance between penicillins and cephalosporins because:
Renal excretion is similar in both classes of drugs.
When these drug classes are metabolized in the liver they both produce resistant enzymes.
Both drug classes contain a beta-lactam ring that is vulnerable to beta-lactamase-producing organisms.
There is not an issue with cross-resistance between the penicillins and cephalosporins.

The reason that two MMR vaccines at least a month apart are recommended is:
The second dose of MMR “boosts” the immunity built from the first dose.
Two vaccines 1 month apart is the standard dosing for all live virus vaccines.
If the two MMR vaccine doses are given too close together there is a greater likelihood of severe localized reaction to the vaccine.
Only 95% of patients are fully immunized for measles after the first vaccine, with 99% having immunity after two doses of MMR.
