The vaccine that is least likely to require booster shots among the options given is the Live attenuated BCG vaccines. The BCG vaccine, which is used to protect against tuberculosis, is typically only given once. It can provide long-lasting protection and booster shots are not usually required.

Here's a brief explanation of each vaccine:

1. Inactivated polio vaccines: These vaccines are often given in multiple doses, with a booster dose given later to ensure continued immunity.

2. Pneumococcal polysaccharide vaccine: This vaccine is also typically given in multiple doses, especially for people with certain health conditions.

3. Live attenuated BCG vaccines: The BCG vaccine is usually given once, often in childhood. It can provide long-lasting protection and booster shots are not usually required.

4. Recombinant SARS-CoV-2 spike protein vaccine: This is a type of COVID-19 vaccine. Given the novelty of the virus, it's still unclear how long immunity will last and whether booster shots will be needed. However, current evidence suggests that booster shots may be beneficial.
