How can a group by clause be modified so the end weeks of the year won't be split?

I have a SELECT statement similar to the following:
SELECT YEAR(transaction_date) AS y,WEEK(transaction_date) AS w, COUNT (*) AS c FROM transaction_data_view WHERE mid = 300 GROUP BY YEAR(transaction_date),WEEK(transaction_date) ORDER BY YEAR(transaction_date),WEEK(transaction_date);
The ONLY problem, here, is that if New Years day occurs in the middle of the week, that week's data will be split at the first second of the New Year. Of course, my real select statement is much more complex than this, involving joins of both tables and views (and it is quick), but this suffices to make the only remaining problem obvious.
If it matters, this is being done in MySQL.
So, how, then, can I fix the GROUP BY and ORDER BY clauses?
