Final answer:
Yes, there are vaccines available for measles, chickenpox, and tuberculosis. These include the MMR vaccine, the varicella vaccine, and the BCG vaccine for tuberculosis, which is used more widely in countries with a high occurrence of the disease.
Step-by-step explanation:
The statement that vaccines are available for measles, chickenpox, and tuberculosis is true. Vaccines such as the Measles, Mumps, Rubella (MMR) vaccine protect against measles. For chickenpox, there is a varicella vaccine. Tuberculosis can be prevented with the Bacillus Calmette-Guérin (BCG) vaccine, which is more commonly used in countries with high prevalence of TB. It's important to note that while some diseases like measles and chickenpox have become less common in the United States due to widespread vaccination, they have not been completely eliminated and vaccination is still necessary.
