The recent resurgence of measles has raised concerns about the effectiveness of old vaccines. With over 95% vaccination coverage in the US, measles is unlikely to spread. However, smallpox is a different story, as there is no more worldwide wild smallpox since 1977. The remaining smallpox viruses are stored in locked containers at two locations, making any future case a bioterrorism attack.
Old vaccines from the 1950s and 1960s for measles and polio are no longer effective against new strains or variants. In the unlikely event of an outbreak, treatment and vaccination would need to be coordinated by local and national health authorities. If you received a complete course of poliovirus vaccination more than 70 years ago, you do not need a booster unless traveling to an area with transmission.
For vaginal itching caused by estrogen blockers in breast cancer survivors, try a vaginal moisturizer containing hyaluronic acid. Nonhormonal treatment has been shown to improve symptoms in 90% of women. If nonhormonal treatment is ineffective, low-dose vaginal estrogen may be recommended, but its safety and risks must be discussed thoroughly with your oncologist.
