Dosage Forms & StrengthsÂ
Injectable Solution (IM)Â
Single dose vialsÂ
0.5 mLÂ Â
Safety and efficacy are not seen in pediatrics who are less than 2 years of age.Â
This is indicated for the prevention of meningococcal disease which is caused due to Neisseria meningitidis serogroups A, C, Y and W-135 in people aged above or equal to 2 years age where the recommended dose of primary vaccination is 0.5 mL where it can be given as a booster dose for individuals who are at high risk of developing meningococcal disease.Â
Recommended immunization or primary vaccination in infants who are between 6 months and 12 weeks of age consists of three doses of 0.5 mL each with first dose from 6 weeks of age followed by 2nd dose after two months followed by 3rd dose after 2 months and 4th dose after 1 year age that is 12 months.Â
Refer to the adult dosingÂ
routine prophylactic use of acetaminophen is avoided, which can reduce the effectiveness of vaccines if given before or after vaccination
vaccination should be given at least 14 days before initiation of cladribine to avoid a reduction in the efficacy of the vaccines
the meningococcal vaccine can reduce the efficacy of the pneumococcal conjugate vaccine
efficacy of vaccines will be reduced when used along with vaccine administration, which should be avoided for at least two weeks before initiation of therapy
immunosuppressants can decrease the efficacy of the vaccines
immunosuppressants can decrease the efficacy of the vaccines
immunosuppressants can decrease the efficacy of the vaccines
immunosuppressants can decrease the efficacy of the vaccines
immunosuppressants can decrease the efficacy of the vaccines
meningococcal conjugate vaccine efficacy can be altered or reduced by tetanus toxoid vaccines
this drug increases the risk of contracting an infection from any live vaccine. So, the administration of the vaccine is recommended only after two months of therapy with elivaldogene autotemcel
Actions and Spectrum:Â
Actions:Â
Formation of bactericidal antibodies after administration of meningococcal A C Y and W polysaccharide tetanus toxoid conjugate vaccine which provides immunity against meningococcal disease caused by Neisseria meningitidis which can be prevented via directing the formed antibodies towards the serogroups A, C, Y, and W-135.Â

Contraindication/Caution:Â
ContraindicationsÂ
CautionsÂ
Pregnancy consideration:Â Â
No data is available regarding the administration of the drug during pregnancy.Â
Breastfeeding warnings:Â Â
No data is available regarding the excretion of drug in breast milk.Â
Pregnancy category:Â
Category A: well-controlled and satisfactory studies show no risk to the fetus in the first or later trimester.Â
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.   Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.   Â
Category N: No data is available for the drug under this category.Â
Pharmacology:Â
meningococcal A C Y and W polysaccharide tetanus toxoid conjugate vaccine is conjugated to tetanus toxoid protein carrier to give immunity against meningococcal disease. Formation of bactericidal antibodies after administration of meningococcal A C Y and W polysaccharide tetanus toxoid conjugate vaccine, which provides immunity against meningococcal disease caused by Neisseria meningitidis which can be prevented via directing the formed antibodies towards the serogroups A, C, Y, and W-135. Â
Pharmacodynamics:Â
Antibodies once formed after meningococcal A C Y and W polysaccharide tetanus toxoid conjugate vaccine can give protection against meningococcal disease that is caused due to Neisseria meningitidis.Â
Pharmacokinetics:Â
Limited data available. Onset of action post vaccination occurs via seroconversion is after 1 month where duration of its action that is antibody waning can seen upto 5 years following primary vaccination where booster dose is recommended to make antibodies persist in the body and this antibody waning may vary with special product and among serogroups.Â
Administration:Â
meningococcal A C Y and W polysaccharide tetanus toxoid conjugate vaccine is carried out its immunization by intramuscular route only. Injection site recommended in infants is anterolateral aspect of thigh and after 12 months children the injection site can also be deltoid muscle.Â
