ATC for influenza vaccines only maps to few meningococcal vaccines

(Oskar Gauffin) #1


I’m looking into the mapping from ATC to RxNorm for the ATC-code J07BB, Influenza vaccines.

I’ve found the ATC-concept-id to be 21601333 and running

select max_levels_of_separation, c.*
from cdm_synthea10.concept_ancestor ca, cdm_synthea10.concept c
where ca.ancestor_concept_id = 21601333 and c.standard_concept='S'
and ca.descendant_concept_id=c.concept_id
order by max_levels_of_separation;

gives me 8 different meningococcal vaccines, e.g. “Haemophilus influenzae b (Ross strain) capsular polysaccharide Meningococcal Protein Conjugate Vaccine Injectable Solution [Enzira]”.

But a search for ‘%influenza%vaccines%’ seems to indicate that there are many other (2870) influenza vaccines in the concept table.

(SELECT * from concept
WHERE concept_name like '%influenza%vaccine%')

Am I doing something wroing, is this a bug or something that simply hasn’t been covered yet in the mapping?

Thank you!

Haemophilus influenzae is a bacteria that was assoicated with influenza long time ago and is therefore historically named in that way. It does not actually cause flu.

Influenza is caused by a virus and ATC “Influenza vaccines” should not include any vaccines containing Haemophilus influenzae. The fact that there are any bacterial vaccines in that category is a mistake.

So it is indeed a bug. We will fix it next update.

Friends: Will be fixed with the next ATC release.

Ok, good to know! By the way, how is the next ATC-release advertised?
