#1. SSRIs. Selective serotonin re-uptake inhibitors better tolerated than other classes of antidepressants ; usually considered first line for treating depression. ALL drugs have side effects.
#2. MMR vaccine. NO evidence of link between measles, mumps, and rubella vaccine and bowel disease OR autism. Safest way to protect children against these infections. Link here.
#3. Influenza vaccine. Generally safe ( even in pregnancy ), if not always effective ( World Health Organization has to predict likely ‘flu strains months in advance, so enough vaccines may be produced ). Link here.
#4. Antibiotics. Vital in treatment of infections for well over half a century. Resistance IS an increasing problem, so must be appropriate for type of infection ( bacterial, viral, fungal, other ). Link here.
#5. HPV vaccine. Human papilloma virus vaccine generally safe. Prevents pre-malignant genital and anal lesions; and cancers, particularly cervical and anal. Link here.
#6. Chemotherapy. Chemotherapy drugs target cancer cells to destroy them and stop them dividing further. Non-cancerous rapidly dividing cells may also be affected, but chemotherapy offers life-saving intervention in MANY cancers. Once they have spread the ONLY hope is for this type of treatment. Increasingly targeted to INDIVIDUAL cancer types and patients ( various forms of biological therapy, although still too expensive ! ). Link here.
#7. Rotavirus vaccine IS a live oral vaccine ( the virus is " attenuated " / weakened ). Protects young children against gastro-enteritis, which may otherwise be fatal. Good safety record. Link here.
#8. Polio vaccine. Polio is essentially a disease of the past, except in countries such as Pakistan and Afghanistan - thanks to vaccines ( oral / Sabin ; and injected / Salk ). Last known cases in Philippines 1993 ; UK 1998. Better to have occasional vaccine side effects than paralysis / death. Link here.
