Does a vaccine provide temporary immunity?

Some vaccinations lose their effectiveness over time, so you could call them temporary. Sometimes this is because the organism mutates and the vaccine is no longer a "fit" to protect against the mutated form, and sometimes it is because our bodies need a "reminder" of the pattern of antibodies that prevent the disease, or sometimes there was not a complete immune response the first time (booster, often needed in children whose immune systems may have been immature when they were given the original vaccination and didn't respond fully). However, many other vaccines provide life-long protection against the infective agent (antigen), such as the commonly given MMR vaccine (measles, mumps, and rubella).
