Detailed explanation-1: -Subunit vaccines are considered promising candidates for developing immunizations against malaria, tetanus, human cytomegalovirus, Salmonella enterica serovar Enteritidis infections, and even the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Detailed explanation-2: -The whooping cough (pertussis) vaccine also does not give lifelong immunity, and that may be one reason why outbreaks still happen.
Detailed explanation-3: -So the correct answer is “ Vaccines are preventive means to fight diseases".
Detailed explanation-4: -Toxoid vaccines The immune response is focused on this specific toxin. Toxoid vaccines do not offer lifelong immunity and need to be topped up over time. Toxoid vaccines are used to create immunity against diphtheria and tetanus.
Detailed explanation-5: -Benefits: Subunit vaccines only contain pieces of a pathogen, not the whole organism, so they cannot make you sick or cause infection. This makes them suitable for people who should not receive “live” vaccines, such as young children, older people, and immunocompromised people.
Detailed explanation-6: -Protein subunit. Polysaccharide subunit. Conjugate vaccine. Peptide subunit.
