Is 'immune serum' the same as a vaccine?

No. A vaccine stimulates your own body to produce long-term active immunity. An immune serum provides ready-made antibodies for immediate, short-term passive immunity.

Can you get immune serum from a pharmacy?

Generally no. It is a prescription-only biological product, often held in hospital pharmacies or specialist centres for treating specific conditions like tetanus, rabies, or venomous bites.

What are the risks of immune serum therapy?

Risks can include allergic reactions (especially to animal-derived serums), serum sickness (a delayed immune reaction), and potential transmission of blood-borne pathogens, though modern products are screened for safety.

What's the difference between 'immune serum' and 'intravenous immunoglobulin (IVIG)'?

IVIG is a more purified and processed product made from the pooled plasma of many donors, containing a broad mix of antibodies. An immune serum is typically raised against a specific pathogen, providing highly targeted antibodies.
